A normal plant cell holds water in the vacuole of the cell. This large organelle also gives the cell support. Suppose a plant is
submerged in salt water. As a result, the vacuoles collapse and the leaves wilt. This condition is called plasmolysis. Which explanation do you think best describes what happens to the cells of that plant during plasmolysis?
Explain that water moves down a water potential gradient, and the salt solution has a lower water potential than the vacuole so water leaves the vacuole through osmosis
In exam Q's key points are: - Water potential gradient - Higher water potential in vacuole - Leaves through osmosis
